What is the function of the renal bark?

The kidney consists of inner kidney medulla and outer kidney cortex closed inside a hard renal capsule. While the kidney medulla contains structures known as Henle collection and loops, the renal bark contains kidney bodies and intricate tubules. Inside the kidney thick blood blood, the blood is filtered in the first part of the urine formation process. The tube then reabsorb useful minerals and nutrients from filtered blood before passing into the Henle loop in Medulle.

There are millions of units known as nephrons in the kidneys. Each nephron contains corpuscl, located in the renal cortex, along with a number of tubules, some of which immerse themselves in Medully. Renal corpuscles consists of what is called glomerulus, a small node of blood vessels, inside a structure known as Bowman's capsule. Blood flows into a glomerulus where there are blood vessels full of small holes. Are too small to allow the blood of Cells to escape, but water, minerals, nutrients and other small molecules are able to pass into the so -called. Bowman's space.

There is a filter membrane between the blood vessels of glomerulus and Bowman space that helps prevent cells and proteins from abandoning the glomerulus. The process that occurs in the renal cortex is sometimes referred to as ultrafiltration and water and molecules in Bowman space are known as filtrate. The filtrate remains in the renal bark for the next phase of urine formation, which includes drainage into the proximal combined tubule.

In the proximal repaired tubule, more useful substances are absorbed from the filtrate and returned to the blood. The cell -lining cells are specially modified so that they can actively draw molecules from the filtrate, followed by part of the water. Furthermore, the urine formation process moves away from the kidneys to Medully, where water is obtained from the filtrate inside the Henle loop. This leads to the distal repaid tubul, which is again in the bark and where other molecules are absorbed.

Finally urine from diIt flows into the collecting channel. While large collection channels are found in Medulle, smaller ones can be placed in the renal cortex. The pipeline is thrown into a space called a renal pelvis, which is connected with urea, a tube that transmits urine from the kidneys and to the bladder.
